BCM5705KFB Dettagli del prodotto

The BCM5705KFB is a fully integrated 10/100/1000BASE-T Gigabit Ethernet media access control and physical layer transceiver solution for high-performance network applications. The BCM5705KFB combines a triple-speed, IEEE 802.3 compliant media access controller (MAC), a PCI bus interface, an on-chip buffer memory, and an integrated physical layer transceiver in a single device. The BCM5705KFB is fabricated in a lowvoltage 0.13µ CMOS process, providing an ultra-low power solution. By itself, the BCM5705KFB provides a complete single-chip Gigabit Ethernet NIC or LOM solution. 

The BCM5705KFB includes a 10/100/1000-Mbps Ethernet MAC with full-/ half-duplex capability at all speeds. Support for the following 802.3 functions is featured in the MAC:

• VLAN tagging

• Layer 2 priority encoding

• Link aggregation

• Full-duplex flow control

The BCM5705KFB continually monitors various channel conditions. The optional wirespeed capability allows the BCM5705KFB to force auto-negotiation to be automatically limited by the speed that the channel can reliably support rather than the performance of the end equipment.
